Joomla shows HTML entity code in menu header instead of the special character
The problem
We want to have a menu with the name "Sun & Fun" in the top menu of the page. The problem is that Joomla by default converts the "&" special character into "&".
The reason
Due to security reasons Joomla converts all special characters into HTML entities (because if it would not do this a user who has permission to create new articles could enter various code into the menu which would run once a user clicks that menu).
But for regular websites where only a web administrator creates new articles this behaviour is not intended.
How can this behaviour be changed in Joomla?
This behaviour can be easily be solved by editing the file
/modules/mod_menu/helper.php
and change this (at around row #112):
$item->title = htmlspecialchars($item->title);
to this:
$item->title = $item->title;
